bbcode-parser-sax - a bbcode parser with no dependencies and a simple API.

bbcode-parser-sax is a bbcode parser, writen with PEGjs. The PEGjs grammar is compiled into a parser library and does not have any dependencies.

The parser outputs a list of events in json, each with a specified type, similar to a SAX parser.

For example, given the string: The quick brown fox [i]jumped[/i] [b]over[/b] the [u]stream[/u], the tool would emit:

[
 { type: 'text', text: 'The quick brown ' },
 { type: 'startTag', tag: { name: 'i', value: null } },
 { type: 'text', text: 'fox' },
 { type: 'endTag', tag: { name: 'i', value: null } },
 { type: 'text', text: ' ' },
 { type: 'startTag', tag: { name: 'b', value: null } },
 { type: 'text', text: 'jumped' },
 { type: 'endTag', tag: { name: 'b', value: null } }
]

Tags that have values, like [url=https://site.com] will be parsed as tag: { name: 'url', value: 'https://site.com' }.

This style allows the parser to be simple, and makes it easy to adapt the output to whatever you'd like!

Installation

A package with both CommonJS and ES Modules is available on NPM. You can install it with yarn add bbcode-parser-sax or npm install bbcode-parser-sax

Building

To build the package from source, run yarn build from the project directory to both generate the parser from the grammar, and to build cjs and esm outputs.

Usage

Usage will depend if you're using this with CommonJS or ESM

For CommonJS:

const {parse} = require("bbcode-parser-sax")
return parse(BBCODE_STRING)

For ESM:

import parser from 'bbcode-parser-sax'
return parser.parse(BBCODE_STRING)

Tests

This package has a few basic tests to confirm the parser is working. Run yarn test to execute the tests.
